Orbital Rhabdomyosarcoma

AM is a 10-year-old boy who was playing with a wiffle ball when it struck his left eye. There was no apparent injury and he continued playing after a few minutes. The next day his parents noted some mild redness and swelling of his lids on that side, but he had no complaints and went off to school. By that evening the swelling had increased dramatically but he mentioned only a mild pressure feeling. The parents were concerned and took him to the emergency room. An ophthalmologist was called in for a consultation and felt the child had suffered an orbital hemorrhage from the ball. A CT scan showed diffuse orbital opacity with increased tissue volume compatible with the diagnosis of hemorrhage (Fig. 154).
